Using a 44 or 44A filter will give the same look as traditional ortho film. Traditional ortho stops recording at approximately 580nm, and at that wavelength the 44 transmits o% and the 44a transmits .1% of the light hitting the filter. That's from the Transmission of Wratten Filters pub by Kodak. It means you'll need to increase your exposure by 1-2 stops, depending on the wavelengths being photographed.
That will give you a more traditional look when developed for your style than if you try a new film and have to relearn its properties, wasting several shots in the process.
